STOCK-BEGULATING MECHANISM FOR PAPER-MAKING MACHINES.

Application med October 31, 1927., Serial- No. 229,940.

The main objects of this invention are:

First, to provide a simple and eifect-ive means for controlling the weight of stock delivered to the stud chest of a paper machine.

making Second, to fiov'ide an improved method or process for controlling the weight of stock. i

the

Objects pertaining to details and economies of constructionand operation of my invention will definitely appear tion to follow. in the claims.

from the descrip- The mventionis pointed out A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, in which:

1isa

Jordan beater of the usual construction supplied from supply chest 2. 21 is the stock pipe delivering into chest. The

the supply Jordan delivers under pressure through the pipe 3 to the regulating stuff chest 4, which is provided with a constant level compartment 41. It has pipe 442. 43 is a regulating discharge pipe from the constant level compartment which Jordan beater and stuff supply box therefor,

delivers into the balanced controlling hopper 5. The hopper 5 has a restricted outlet 51.

These deliver into the charge through the pipe 8 of a paper making machine,

The balanced hopper 5 issupported lever 10 which is hopper 6 an d dis- 7 to thestuif chest by the fulcrumed at 101 onthe bracket 9, and is provided with an adjustable counterweight 102.

This lever 10 operates the lever 11 through the connecting link 111.

The lever 11 controls the supply of water through the pipe 12 by controlling the needle "alve 13 which is of usual construction controlled by the reciprocation of the lever 11,

the valve stem 131v being connected to end 112 of the said the lever 11. The valve 14 is provided to cutoff pipe 12 which delivers water through a restricted pipe 15.int-o the supply chest 2 to cause, jet action to facilitate the admixture of the water with the stock at that point.

weight of paper the control of stock is automatic by the weight of the stock itself. The

balanced hopper operates the lever 10 which, through its connections to the lever (thesepartsconstituting a compound lever) ,opens the needle valve when the stock is heavy,

and

Q Having bination with ally closes the needle valve 13, thus lessening or stopping the dilution as soonas the stock is sufficiently diluted,

B this means the weight of stock is regulate and the variation in weight of the sheet delivered from the' paper machine is controlled within very narrow limits, and the paper stock is thus conserved.

I claim as new and desire to secure by Letters Patent is:

thus described my invention whatv 1. In a stock-control means for paper mak- 'ing machines, the combination with the of a regulating supply chest with a constant level chamber, delivery pipes therefrom, a balanced hopper with restricted "outlet, a counterbalanced lever carrying said hopper, a water supply pipe, a needle valve for controlling the same, and connections from said valve to the said counterbalanced lever, as specified.

2. In a paper stock control means, the combination of a constant level regulating supply chest, a counterbalanced hopper for receiving stock therefrom, a water supply pipe for delivering water directly to the paper stock supply, a needle valve, and a lever connection from the said hopper to control said valve to regulate the opening.

3. In a paper stock control means, the comthe Jordan beater and stufl supa regulating supply chest delivery connections from said Jordan beater to said regulating supply chest, a counterbalanced hopper with restricted discharge opening, a delivery pipe from the regulating chest to the said counterbalanced hopper, a water supply pipe, and a valve with connections to the counterbalanced hopper to control the water supply to the Jordan beater, as specified.

4. In a paper ply box therefor,

stock control means, the combination with the Jordan beater and stufi water supply pipe, and a Valve with consupply box therefor, a regulating supply nections to the counterbalanced hop r to chest, a delivery connection from said Jordan control the water supply. to the Jordan ater, 10 beater to said regulating supply chest, a as specified.
